Rice fermentation substance and rice bran extract freeze-dried powder and preparation method

Abstract

The present invention discloses rice fermentation substance and rice bran extract freeze-dried powder. The freeze-dried powder comprises the following components in percentage by mass: 4-5.5% of mannitol, 2.5-4% of trehalose, 1.5-2.5% of sodium hyaluronate, 0.03-0.07% of adenosine, 0.03-0.07% of xanthan gum, 1.5-2.5% of amino acid, 1.5-2.5% of pyrrolidone carboxylic acid, 1.5-2.5% of lactate, 1-1.5% of ceramide phosphorylethanolamine and 83-86% of water. The preparation method of the freeze-dried powder comprises the following steps of S1, weighing raw materials, stirring the raw materials ata constant speed, and performing heating to obtain a transparent solution I; S2, cooling the transparent solution I; S3, filtering the transparent solution I; S4, weighing the raw materials, adding the raw materials into the transparent solution I, stirring the raw materials at a constant speed, and performing heating to obtain a transparent solution II; S5, cooling the transparent solution II; S6, filtering the transparent solution II; S7, cleaning a penicillin bottle and performing drying sterilization; and S8, filling the penicillin bottle with the transparent solution II, and performing freeze-drying. The freeze-dried powder has the advantages that the effective components are high in stability and difficult to denaturize and inactivate, and the freeze-dried powder is convenient to carry and store.

Description

technical field [0001] The invention relates to the technical field of freeze-dried powder, in particular to a freeze-dried powder of fermented rice and rice bran extract and a preparation method thereof. Background technique [0002] Rice fermented product is a natural fermented product of rice bran, which has the effect of whitening, inhibits the growth of melanin, and can also inhibit the activation of tyrosinase; it can promote the production of cholesterol and ceramide, which are the components of sebum. An important component, the increase in their content helps to improve the softness of the skin, so it has a conditioning effect; it has an activation effect on glutathione reductase, combined with its antioxidant properties, it has a revitalizing effect and can be used for anti-aging senescence. Existing cosmetics containing fermented rice products are mostly essences or emulsions, which cannot effectively protect the active ingredients in fermented rice products. At ...
